Hi Genius people,

I am new to UVC. I have little bit experience with USB devices. I am using EZ-USB FX3 board (dev kit with a MIPI sensor).

What i am trying is to create 2 separate devices with a YUV 1080p stream from each. I am trying to prototype this and followed the "USBVideoClassBulk.zip" sample code.

(This sample produces the MJPEG stream).

I modified the descriptors to have 4 interfaces with 1 control and 1 streaming interface for each stream. But my device enumeration fails and I get "reset" request from the Windows PC. Can any one help me with some tips and sample descriptors.

I really appreciate all the help and support.

Regards,

Ragini

Hello Ragini,

The Fx2g2UvcDemo example firmware that comes with the FX3 SDK implements streaming hard-coded YUY2 format image data in USB 2.0 mode. I have attached a project file that implements the same in USB 3.0 mode as well so that it can be used in FX3 or FX2G2.

Best regards,

Srinath S
